BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 589,220, dated August31, 1897.

Application filed June 14, 1897. Serial No. 640,622. (No model.)

T 0 all whom it may concern.-

Be it known that I, WILLIAM A. PENFIELD, of Meriden, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inBicycle-Bells; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a view in side elevation of a bell constructed in accordancewith myinvention; Fig. 2, a View thereof in vertical section; Fig. 3, aplan view with the gong removed; Fig. 4, a detached perspective View ofthe carrier; Fig. 5, a detached perspective View showing thetwostrikers; Fig. 6, a view in longitudinal central section of the carrier.

Myinvention relates to an improvement in bicycle-bells, the object beingto produce therefor a striker constructed with particular reference tomaking it as heavy and hence as powerful in action as is possible,consider-v ing the space available for its occupancy and operationwithin the bell.

A further object of my invention is to produce a striker adapted to beconfined in place by simple and durable means.

With these ends in view my invention consists in a bell having certaindetails of construction, as will be hereinafter described, and pointedout in the claims.

In carrying out my invention, as herein shown, I employ two flatstrikers A and A, which are, so to speak, matched or fitted together soas to secure a great economy of space, whereby, considering the spaceavailable, they may be made heavy and hence powerful in the blowsdelivered by them. As shown, each of the said strikers hasa roundedcentrally-arranged striking-surface A located at the outer end of itsbody portion, and an abutment-shoulder A located at the inner endthereof. Each striker is also formed with an arm the outer edge of whichis made straight, while its inner edge is cut away to form aclearance-space a, adapting the arm to clear the gong-post B. The endsof the said arms are formed with inwardly-projecting stop-lugs A andsquare abutment-faces a the face a of the striker A coacting with theshoulder A of the striker A, and the face a of the striker Acoactingwith the shoulder A of the striker A. The said strikers are, as to theirstop-arms, rights and lefts, so to speak, so that their respectivestop-arms may extend beyond each other, whereby the strikers are matchedor fitted together, so as to occupy the minimum of space. The strikersare mounted for longitudinal reciprocation upon a sheet-metal carrier C,furnished along its sides with guiding-fingers C, located at equaldistances from each other and six in number, three on each side. Thiscarrier is also provided with a pinion C the hub C of which extendsupward through it to form a long bearing for the rotation of the carrierupon the said post 13, which is rigidly secured within the cup-shapedbase D of the bell. The said carrier is rotated upon the stud B by meansof an operating mechanism which may be of any suitable character andwhich consists, as herein shown, of awheel E, meshing into the pinion Caforesaid, and provided upon its lower face With a pinion E, the teethof which are intermeshed with the teeth of a segmental rack F, formed atthe inner end of the operating-lever F, which is pivotally hung upon astud F located near the edge of the cup-shaped base D, the flange D ofwhich is formed with a slot D for the outward projection and clearanceof the fingerpiece F of the said lever. A coiled spring G, connectedwith the lever at one end and at the other with a pin g in the base D,provides for operating the lever in one direction. The gong H is ofordinary construction and formed with a tapped hub 11, adapting it to besecured to the threaded upper-end of the post B. It is also provided, inthe usual mannor, with an inwardly-projecting striking-lo g h, formednear its edge, and in position to be sharply struck by the roundedstriking-faces A of the strikers.

The two strikers are held down in place upon the carrier by means of aWasher I, a coiled spring 1, bearing upon the upper face of the washerand encircling the post 13, and a nut I, mounted upon the post andadjustable thereupon for regulating the tension of the spring, whichpresses the washer down upon the inner ends of the strikers, so as toprevent them from moving too easily, but without imposing enoughrestraint upon them to prevent them from reciprocating as required forthe operation of the bell.

It will be understood that as the carrier is rotated by means of thefinger-lever F the two strikers are thrown outward by centrifugal force,their outward movement being limited by the engagement of theinwardlyturned stop-lugs a of their stop-arms with the post B atopposite points thereon. WVhen the strikers strike the lug h of thegong, they are thrown inward, their inward movement being limited by theengagement of the abutment-faces a of their stop-arms with theabutment-shoulders A of their body portions. The clearance-spaces a,formed in the inner edges of the stop-arms, permit the strikers toreciprocate with sufficient range for all purposes. By constructing andarranging the strikers as shown I am enabled to make them relativelylarge and heavy and hence powerful in their striking action and durable.

It isapparent that the carrier and the other details of the bell maybevaried without departing from my invention, and I would therefore haveit understood that I do not limit myself to the exact constructionherein shown, but hold myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of my invention.Thus, if desired, I may use one striker instead of two, although Iprefer to employ t'wo.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a bicycle-bell, the combination with the gong-post and gongthereof, of a carrier rotating upon the gong-post as upon a center,means for actuating the said carrier in rotation, and one or morestrikers mounted upon the carrier for reciprocation thereupon,

and each having an arm which extends to one side of and beyond thegong-post.

2. In a bicycle-bell, the combination with the gong-post and gongthereof, of a carrier rotating upon the gong-post as upon a center,means for actuating the said carrier in rotation, and one or morestrikers mounted upon the carrier for reciprocation thereupon, eachhaving an arm which extends to one side of and beyond the gong post, andwhich is form ed with a clearance-space for clearing the gong-post, andwith a stop-lug for coacting with the gong-post.

3. In a bicycle-bell, the combination with the gong-post and gongthereof, of a carrier rotating upon the gong-post as upon a center,means for actuating the said carrier in rotation, and two strikersmounted upon the carrier for reciprocation thereupon, and each havingastop-arm arranged to extend to one side of and beyond the gong-post, thestoparms being rights and lefts so that the two arms are respectivelylocated on opposite sides of the post, and means for holding the saidstrikers down upon the carrier under frictional restraint.

In a bicycle-bell, the combination with the gong-post and gongthereof, of a carrier rotating upon the gong-post as upon a center,means for actuating the said carrier in rotation, two flat strikersmounted upon the carrier for reciprocation thereupon, and each having astop-arm arranged to extend to one side of and beyond the gong-post onthe opposite sides of which the arms of the respective strikers arelocated, and adjustable means applied to the post for holding thestrikers down upon the carrier under frictional restraint.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
